Mac versus Windows vulnerability stats for 2007

For all the talk that I continue to hear about how Windows is not a safe operating system, I'm really glad to see independent groups such as ZDNet putting out studies such as this one:

I love this chart from the article:


It shows that OSX had (on average) roughly 5.5 times as many flaws per month as Windows XP and Windows Vista combined!  The staggering number for me is 234 highly critical (or worse) flaws in OSX compared to 27 in Vista and XP combined (some of which look to me to be double counted between Vista and XP).

    I love the chart too… if only the sum column represented the sum of the rows above them!  Not a very effective table as long as the numbers don’t add up.

    Good catch!  I didn’t author article or the chart, but I summed his data myself – here are the results:

    Total Vista = 27 (7 less than in the chart)

    Total XP = 15 (5 less than in the chart)

    Total Vista + XP = 34 (10 less than in the chart)

    Total OSX = 234 (same as in the chart)

    I wonder where his discrepancies came from?  he reports more than his totals for Windows but his numbers for OSX match…

    These numbers may not be all that they seem. They have been dissected by a mac fan-boy which shows the numbers may well be bogus. Still, interesting reading:

    I can see this yes, but I would also like you to find some graphs that show the number of malware and virus for each platform as well…

    Security isn’t JUST measured by how many vulnerabilities that are fixed or found for an OS, but the actual execution and usage of those…

    I’m not a Mac zealot, but I will say that with no anti-virus and spyware protection, my mac has been used by ALL of my friends (internet smart and not) and I have had ZERO problems…
